maybe this has nothing to do with the ICS ROM,
because I noticed this behavior from the the first ICS builds up to now:

when I try to navigate with Google maps I noticed that always around 2 to 3 minutes of navigation the GPS loses it fix,
when I immediately try the GPS signal with a program like "GPS test" it shows that there is nothing wrong with the GPS signal itself.
Restarting Google maps again will show the satellites without any problem.
This happens always (I tried it at least 15 times) and is very reproducible.

I seems just like the GPS module gets into a sleep-mode using the Google maps navigation after a few minutes.
Could this be related to some power management setting in ICS ??

I don't use Google maps but motonav (offline navigation). Should say never have a problem with GPS. Yesterday driven 3 hours from Netherlands to Luxembourg without any problems
